What is the y-coordinate of the midpoint of a segment with endpoints (0, -4) and (-4, 7)? show your work.

the solution is h=10 because you add 9 to each side of the equation.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
